+% Description:
+%
+% This command includes a list of pgfplots library files. For each file X in the
+% list, the file tikzlibrarypgfplots.X.code.tex is included, provided this has
+% not been done earlier. 
+%
+% For the convenience of Context users, both round and square brackets
+% are possible for the argument.
+%
+% Example:
+%
+% \usepgfplotslibrary{units}
+% \usepgfplotslibrary[units,dateplot]
